ABSTRACT:

SLOTTING ATTACHMENT by Arnold Throp Ram. 11 Set the steel for the ram to run as true as possible In a four-jaw chuck and fix up a three-point or four-point steady to support the other end. There is a problem getting the fingers of a steady set equi-distant from the imaginary line in space joining the. DEBURRING TOOLS FOR SLOTTING ATTACHMENTS OF B&S AND SWISS MACHINES These high speed steel circular deburring tools ﬁ t the slotting attachment of B&S Screw Machines and Swiss Machines and remove cut-off burrs from the back end of the part completely, smoothly and uniformly.

There is the number of machine instruments creating round and decrease gaps. Be that as it may, numerous building parts require square and non-roundabout openings. At exhibit square and other non-openings are delivered utilizing CNC machines or start disintegration or opening machines. However, there is no quality machine apparatus to deliver square and polygon openings at least cost. In this way, we influenced an endeavor to configuration to and manufacture a connection for penetrating machine which would deliver square and polygon openings considerably more effective than the present strategy. This will be extremely helpful to situate joltheads and so on.

This connection can be however of a reversal of the “Cam and Ball instrument. This connection can be fitted either in the boring machine or vertical processing machine. A total outline for this connection for a size of greatest 20mm square and polygon gaps has been effectively done and tried utilizing an upright penetrating machine. For various sizes of gaps under 20mm the device can be changed. Comparable outlines can be made for any size and any number of sides to maintain a strategic distance from the part of setting time and pre-machining strategies associated with current techniques and extremely valuable if there should be an occurrence of large-scale manufacturing.

PRESENTATION:

Coimbatore is a very modern city. This is for the most part because of a business of neighborhood people groups. As there is no open segment undertaking. The little scale ventures, however, have a machine and other universally useful machine apparatuses; they think that it is hard to get a decent completed square and polygon forming the parts. For delivering square and polygon openings we have the opening and suggesting machines. Yet, it is the moderate process, the cost is high and setting time is more. A great deal of time and manual work is associated with these techniques.

So this venture “FABRICATION OF SLOTTING ATTACHMENT IN DRILLING MACHINE” is particularly helpful, on the off chance that it is given great quality frame instruments of various shapes and sizes. Thus a need exists for connection which can create non-roundabout openings at least cost. Therefore an endeavor is made to plan and manufacture such a connection.

WORKING PRINCIPLE:

To acquire a gap of wanted shape, first, the greatest size of the opening that can be engraved in it is bored utilizing a regular boring tool. Presently without changing the activity and axle settings, the decrease shank of the shaft is brought into the axle. At the point when axle pivots the pole gets the drive and transmits it to the sleeve. The opposite end of the sleeve is associated with the fundamental shaft which is comprised of gentle steel 15 mm shaft. The slant rigging and cam component are utilized to exchange the revolving mintont in to the responding movement.

In, this way the stub responds three times for every transformation of the sleeve. The descending stroke is the cutting stroke. Hence the apparatus responds with little abundancy and high recurrence. The stroke length is equivalent to separate between the upward and descending development of the wrench shaft.

ADVANTAGES:

The precision of shape.

Similarly less work cost than different techniques.

Less physical and mental exhaustion.

Screws and nuts can be effectively situated.

Machining time is less.

DISADVANTAGES:

Not all that compelling for hard materials.

Bolster ought to be given irregularly.

Over-burden ought to be evaded.

Chips stay in the opening.

At the point when this unit was finished and tried utilizing an Upright Drilling Machine vibrations where experienced because of the outspread play of the interior parts. Hence the square couldn’t be machined with that much precision. Subsequently to conquer this imperfection a thin walled round and the hollow empty sleeve has been presented between the packaging and sleeve. The tube shaped sleeve and the inner parts have less leeway just to enable them to turn and no spiral play. Along these lines, the vibrations have been captured. The material utilized of the sleeve is Mild Steel.

DIFFERENT APPLICATIONS:

This boring machine connection should be used for different purposes other than machining structure openings. This unit takes out the nearness of opening machine in the machine shop. Obviously, it may not be valuable for every one of the occupations that a slotter can perform. This is a direct result of the absence of unbending nature that a slotter has. Yet, for little employment works like machining a keyway and so on can be extremely very much performed by utilizing an appropriate device bit settled in the instrument holder utilizing a bar. Presently also by giving a high RPM and least sustain the recurrence of response can be expanded. At the point when this high recurrence response are connected at work through a grating slurry, a pounding impact happens on the work piece and any convoluted shape in the instrument can be delivered in the activity as a female piece of the device. The grating slurry comprises the blend of water and rough particles. This slurry and work piece is encased in a holder.

Lathe Machine:

Lathe is one of the most versatile and widely used machine tools all over the world. It is commonly known as the mother of all other machine tools. The main function of a lathe is to remove metal from a job to give it the required shape and size. The job is securely and rigidly held in the chuck or in between centers on the lathe machine and then turn it against a single-point cutting tool which will remove metal from the job in the form of chips.

For performing the various machining operations in a lathe, the job is being supported and driven by any one of the following methods.

1. Job is held and driven by chuck with the other end supported on the tailstock center.

2. Job is held between centers and driven by carriers and catch plates.

3. Job is held on a mandrel, which is supported between centers and driven by carriers and catch plates.

4. Job is held and driven by a chuck or a faceplate or an angle plate.

The above methods for holding the job can be classified under two headings namely job held between centers and job held by a chuck or any other fixture. The various important lathe operations are depicted in Fig. (a), (b) and (c).

The operations performed in a lathe can be understood by three major categories.

(a) Operations, which can be performed in a lathe either by holding the workpiece between centers or by a chuck are:

1. Straight turning –

Turning is the operation in which a cylindrical surface is produced. The workpiece is supported between centers or in any other work holding device and rotated at the desired speed. The tool is first given a depth of cut by using the cross slide motion of the carriage and then given an axial feed by hand or power. Which can be made to overlap to produce a cylindrical surface on the workpiece by adjusting the feed and having a large nose radius. Repeated cuts may be necessary to obtain a desired reduction of size. A final finishing cut may be given to the workpiece with a low depth of cut and feed but high speed to attain the desired degree of surface finish.

2. Shoulder turning

3. Taper turning –

Taper turning is the process of producing external and internal conical surfaces by combining the rotation of the job and the relative angular feed of the tool. Tapers are used on many tools and machine components for alignment and easy holding. Such as the shank of twist drills, end mills, and reamers, spindles of lathe and drilling machine.

4. Chamfering –

Chamfering is the process of beveling the extreme ends of a workpiece. It is done to remove the burrs, to protect the end of the workpiece from being damaged and to have a better look.

5. Eccentric turning –

It is a turning operation in which turning is performed at a different axis on a single setting of a job. This method of turning is generally used to produce crankshafts and camshafts.

6. Thread cutting –

The process of making threads on a cylindrical job is called threading

7. Facing –

Facing is an operation used to produce a flat surface at right angles to the rotational axis of the job. In this case, the tool is fed at right angles to the job while the depth of cut is provided by the axial motion of the carriage. The job may be held in a chuck or between centers. In this center about half of the front cone is removed to give access to the tool.

8. Forming –

It is a process in which a convex, concave or any irregular surface is formed on the workpiece with the help of a forming tool. The forming tool having the required shape is used to perform forming operation.

9. Filing

10. Polishing

11. Grooving –

The process of creating a narrow slot on the workpiece is called grooving. It is also known as recessing or necking

12. Knurling –

Knurling is the process of embossing a diamond-shaped pattern on the cylindrical surface of a workpiece. Knurling is done on the workpiece so that it does not slip when held and operated by hand. The workpiece is supported in the chuck but since quite heavy forces are involved in the knurling process an additional support is generally provided at the free end with the tailstock center.

13. Spinning –

SPINNING is a method of forming sheet metal into seamless, axisymmetric shapes by a combination of rotation and force. Based on techniques used, applications, and results obtainable, the method can be divided into three categories: Manual spinning, Power spinning, Tube Spinning.

14. Spring winding

(b) Operations which are performed by holding the work by a chuck or a faceplate or an angle plate are:

1. Undercutting –

In the undercutting operation, we enlarge the diameter if done internally and decrease the diameter if done externally. It is done at the end of the hole, near the stepped shoulder of a cylindrical surface and the end of a threaded portion in the blot.

2. Parting-off –

The part is removed so that it faces the ends. For this, the parting tool is involved in slowly to make operate. To cut deeper the parting tool is pulled out and transferred to the side for the cut and to prevent the tool from breaking.

3. Internal thread cutting

4. Drilling –

The workpiece is held in a chuck or on a faceplate and the drill is held in the tailstock quill or a drill chuck held in the quill. The taper in the quill ensures that the axis of the drill is concentric with the rotational axis of the spindle. Feeding is done by movement of the tailstock quill. Reamers, counterbores and other cutting tools may also be used similarly in place of the drill.

5. Reaming –

The process of enlarging the holes to accurate sizes is called reaming. Reaming is always performed after drilling operations. It is similar to the drilling process. The reamer is held in the tailstock to carry out reaming operation.

6. Boring –

Boring is the process of enlarging a hole produced by drilling, casting, punching or forging with the help of a single point tool. Boring cannot originate a hole. In boring the job is held in a chuck or faceplate and a boring tool held on the tool post is fed into it. The operation is similar to external turning in that the feed and depth of cut are given by the longitudinal and cross-motions of the tool respectively. Since the enlarged hole is being generated with a motion of the workpiece about an axial motion of the tool.

7. Counter boring

8. Taper boring

9. Tapping

(c) Operations which are performed by using special lathe attachments are:

1. Milling –

The milling machine lathe attachment is attachable to an existing milling machine to eliminate the need for an operator owning both a milling machine and a lathe. It is designed to be mounted to the side of the milling machine and to be used without disturbing a setup in the associated vise. You can read more about milling machine attachment here.
